The key is not whether the feelings can be articulated but rather whether the feelings can be felt.

If the therapist screens for a dissociative disorder, as is the custom, and finds no formal dissociative disorder, the EMDR will likely assist. If dissociation is present, a more complex approach is required, in which the therapist should be fluent. There may well be strong emotions involved. Strong emotions don't hurt people, unless they are blocked. That's why we tell people to "just notice it" and say it is like "scenery through a train window." This stance will enable ease of processing.
